As an integrated part of the annual National Accounts Supply and Use Tables(SUT) are a final and balanced presentation of the economical categories in the composition of GDP, structured in details by groups of products and services, economic activities and categories of the final consumption. They are elaborated and improved in compliance with internationaly adopted methodological principles and standarts of the European System of National and Regional Accounts(ESA'95, before 2010 and ESA'2010 from 2010 onwards - Eurostat edition) and of the System of National Accounts,(SNA'93, before 2010 and SNA'2008 from 2010 onwards) - a colaboration of the UN, OECD, Eurostat, IMF and the World Bank. SUT are based on the concepts and definitions for treating the transactions, the economic individuals and the classificatory principles of statistical units' grouping as they are applied in elsewhere in the System. Data are presented at basic price, including valuation to purchasers price for the Supply table and in purchasers price for Use table.

Classification system

The European System of Accounts (ESA) 2010 is based on Nace Rev 2 and CPA. The data refers to years 2010 onwards with the ESA 2010 methodology. Supply, use and input-output tables distinguish 64 industries and 64 products. Data before 2010 are available under ESA1995 . Classifications used in this domain:Classification of Economic Activities (Nace Rev 2 from 2008 onwards and Nace Rev 1 for the years before 2008) ; Classification of Products by Economic Activitie(CPA)s;Nomenclature of Industrial Production (PRODCOM);Nomenclature of agriculture, forestry and fishing products (PRODAGRO);Classification of Individual Consumption According to Purpose (COICOP);Classification of the Functions of Government (COFOG);Classification of the Purposes of Non-Profit Institutions Serving Households (COPNI).

Total Economy

Statistical concepts and definitions

Supply and Use tables are matrices by industries and products describing production processes and the transactions in products of the national economy in detail. These tables show:

a) the structure of the costs of production and the value added that is generated in the production process;

b) the flows of goods and services produced within the national economy;

c) the flows of goods and services with the rest of the world.

The ESA 1995(Regulation 2223/96 of the European Council) for the SUT before 2010 and ESA 2010(Regulation(EU) 549/2013 of the European Parliament and of the Council) for the tables from 2010 onwards may be referred to for specific explanations concerning contents of the tables.
